1. A method comprising:

  • generating a data frame having data information at a processor;

    storing the data frame in a memory;

    providing the data frame to a processor interface having a segmentation engine and a direct memory access (DMA) engine;

    segmenting the data frame into a plurality of cells at the processor interface using the segmentation engine and the DMA engine; and

    injecting each of said cells into a cell input engine by transferring each of said cells to a number of memory locations by DMA transfer within a cell memory; and

    establishing a series of linked list pointers associated with said memory locations, wherein said series of linked list pointers includes a logical queue;

    wherein the number of memory locations is based on a length of the data frame.
